Tsev Aging Resistant Polyurea Khoom

Kev sib piv ntawm cov cuab yeej tiv thaiv thaiv tsev

Cov kab dej muaj zog tsis zoo: kev siab tawv asphalt yob, cov tshuaj yaug tsis ruaj khov, cov tshuaj tua tsis sib haum, cov nplaum tsis sib haum, cov ntawv ntim polyethylene thiab EVA cov nplooj ntawv muaj ntau cov pob qij txha, tsis sib haum qis, yooj yim mus xaim thiab hla dej, thiab tsis tshua muaj dej tsis zoo. Lawv yog cov "raincoat" tsis muaj dej yaug thiab tsuas yog tsim rau cov dej tau ntsib.

Txau polyurethane elastomer thiab tshuaj tsuag polyurea elastomer txheej compact, seamless, muaj zog cog qoob loo, muaj dej tsis ruaj ntseg; Tshwj xeeb, polyurea elastomer txheej muaj lub zog tensile siab, loj loj txhav thiab muaj zog cog qoob loo, uas yog tiag tiag "tawv nqaij" tsis muaj dej, thiab siv tau rau dej ntsib txoj dej thiab dej dej rov qab.

Kev kub thiab tsis kub tsis txaus: piv nrog high ntom polyethylene daim ntawv thiab polymer hloov asphalt yob, polyurethane, polyurea elastomer muaj zoo heev thiab tsis kub. Nws tuaj yeem tiv taus siab kub ntawm 160 C thiab nyob twj ywm rau ntawm -40c.

Kuj ua rau pob zeb ntes. Cov tshuaj txau polyurethane muaj qhov siab lub zog (> 17 mpa), siab elongation nyob rau ntawm rupture tus nqi (> 500%), muaj zog compressive zog (daim ntawv cog lus nrog cov khoom siv> 5 mpa), siab hnyav, mus rau pob zeb ntes tawg, ntes cov pob zeb tiv thaiv thiab tawg, nplhaib kho thiab kev txhawb zog ntawm cov qauv yooj yim.

Lub ntes tsis haum ntawm cov dej tsis muaj dej (uas yog, kev muaj peev xwm los tiv thaiv coagulation los ntawm tawg) nyob ntawm lub zog tensile, txheej thickness thiab tsevneeg lub zog ntawm cov khoom. Lub zog ua kom muaj zog ntawm polyethylene thiab polymer hloov asphalt yob yog qhov tsawg heev, yog li qhov kev sib xyaw ua haujlwm tsis zoo. Polymer-modified asphalt waterproof xu khoom, polyurethane waterproof coatings muaj tsawg tensile zog thiab tsevneeg muaj zog, yog li qhov cracking kuj tsis zoo. Polyurea muaj lub zog tensile muaj zog, muaj kev sib zog ua kom quab yuam thiab zoo tawg ntho. Vim nws txoj kev ceev ceev, kev siv sij hawm luv luv thiab kev ua haujlwm siab, polyurea kuj tsim kho thiab kho cov vaj tse qub thiab cov vaj tse.

Lub zog lub zog ntawm polyurea on pob zeb ua ke yog mus txog 5MPa, uas yog siab dua lub pob zog ntawm pob zeb qhob (txog 2.5mpa). Yog li, thaum lub pob zeb ua kom cov pob zeb tawg thiab cov txheej tsho, nws tsuas coagulates cov neeg nyob ze ze lub kwj, kom tsis txhob muaj "hauv qhov chaw" thaum hos lwm qhov chaw tseem ruaj khov kho, uas yog qhov "hom tawv nqaij" tsis muaj dej.

Cim npe nrov: lub tsev laus tiv thaiv polyurea khoom, Tuam Tshoj, lwm tus neeg, lag luam wholesale, txheej
